REG3AAntibody Product Information
Immunogen:Recombinant Rat REG3A protein (Catalog#80258-R08H)
Clone ID:02
Ig Type:Mouse IgG1
Concentration:
Formulation:0.2 μm filtered solution in PBS
Preparation:This antibody was produced from a hybridoma resulting from the fusion of a mouse myeloma with B cells obtained from a mouse immunized with purified, recombinant Rat REG3A (rh REG3A; Catalog#80258-R08H; BAA04904.1; Met1-Gln174). The IgG fraction of the cell culture supernatant was purified by Protein A affinity.

ELISA: 0.5-1 μg/mL

This antibody can be used at 0.5-1 μg/mL with the appropriate secondary reagents to detect Rat REG3A. The detection limit for Rat REG3A is approximately 0.078 ng/well.

Storage:This antibody can be stored at 2℃-8℃ for one month without detectable loss of activity. Antibody products are stable for twelve months from date of receipt when stored at -20℃ to -70℃. Preservative-Free.
Sodium azide is recommended to avoid contamination (final concentration 0.05%-0.1%). It is toxic to cells and should be disposed of properly. Avoid repeated freeze-thaw cycles.
Background

Regenerating islet-derived protein 3-alpha, also known as Regenerating islet-derived protein III-alpha, REG-3-alpha, REG3A, and HIP, is secreted protein which contains one C-type lectin domain. REG3A is constitutively expressed in intestine, and is a pancreatic secretory protein that may be involved in cell proliferation or differentiation. It is overexpressed during the acute phase of pancreatitis and in some patients with chronic pancreatitis. REG3A and REG1A proteins are both involved in liver and pancreatic regeneration and proliferation. REG3A is also a stress protein involved in the control of bacterial proliferation. REG3A is down-regulated in most primary human gastric cancer cells, and might be useful in the diagnosis of gastric cancer. Additionally, REG3A is a target of beta-catenin signaling in Huh7 hepatoma cells. The REG1A and REG3A are downstream targets of the Wnt pathway during liver tumorigenesis.
